The Fish River Canyon in southern Namibia is one of the planet’s most remarkable landforms, stretching across vast terrain in the Richtersveld Transfrontier Park. It is one of Africa’s largest canyons, carved over millions of years by the Fish River as it etched a deep, twisting gorge into the desert plateau. From high viewpoints like Hell’s Bend, visitors can see layers of rock dropping away to reveal ridges and ravines that seem to go on forever, all under wide, open skies.

Morne Rouge Bay is a sheltered beach on Grenada’s southwestern coast, just south of Grand Anse and near the community of Morne Rouge.
